The 200-lb block of Fig. is sitting on a 30° in- clined surface. The coefficient of friction between the block and the surface is 0.50. A light, inextensible cord is attached to the block, passes around a frictionless pulley, and is at- tached to a second block of mass M. Determine the mini- mum and maximum masses, Mmin and Mmax, such that the system is in equilibrium. Is impending motion by slipping or by tipping? 1.5 ft 200 lb 2ft M 30
